The lens drive device (101) has a lens holding member (2) provided with a holding section (72A). A part of the extending part (33A) of the coil (3) is wound on the holding part (72A) to form a winding part (33m). The winding portion (33m) is soldered to an inner portion(26i) of the lower leaf spring (26A). A first quadrilateral hole (26j1) and a first circular hole (26k1) are formed in an inner portion (26i) of the lower leaf spring (26A). The first circular hole (26k1) is disposed between the brazing portion (26s) of the inner side portion (26i) and the first quadrilateral hole (26j1). A first protrusion (2p1) inserted through the first circular hole (26k1) isformed in the lens holding member (2). The inner side portion (26i) and the lens holding member (2) are adhered and fixed to each other by means of an adhesive applied to the first quadrilateral hole(26j1) and the lens holdin
